Fedora directory users - Jun 2008 - MMR issue

Hi Guys,
 
I am stuck in a very crucial FDS server issue, it would be great if any one of
you can help me somehow.

We are upgrading from Fedora Directory Service from 1.0.4 to 1.1.0-3

We have one existing Server with 1.0.4

Now To one server we have initialized the data base and we were able to load the
full DB. But, and when we start the replication we see the following error, and
the incremental update is not happening.

We are going for a multi master replication.


Here is the error.

On Supplier: (FDS Version 1.0.4) OS: Red Hat Enterprise Linux ES release 4
(Nahant)


[17/Jun/2008:11:23:35 +051800] NSMMReplicationPlugin -
agmt="cn=Replication_to_10.91.X.Y" (10:8888): Unable to acquire
replica: Excessive clock skew between the supplier and the consumer. Replication
is aborting.

[17/Jun/2008:11:23:35 +051800] NSMMReplicationPlugin -
agmt="cn=Replication_to_10.91.X.Y" (10:8888): Incremental update
failed and requires administrator action



On consumer: (FD version 1.1.0-3) OS: Red Hat Enterprise Linux Server release
5.1 (Tikanga)



[17/Jun/2008:11:12:59 +051800] NSMMReplicationPlugin - conn=46251 op=1975
replica="o=TejaUsers": Unable to acquire replica: error: excessive
clock skew

[17/Jun/2008:11:23:34 +051800] - csngen_adjust_time: adjustment limit exceeded;
value - 86401, limit - 86400

[17/Jun/2008:11:23:34 +051800] NSMMReplicationPlugin - conn=46461 op=792
replica="o=TejaUsers": Unable to acquire replica: error: excessive
clock skew


Now, My doubt is we succeded in a test environment with the same, with the only
diference that we had the same OS in both the server, rest all same. Our servers
are perfectly synced with NTP also.

Please help in this scenario..

Did you try the workaround in the bug report I sent to you on the
Redhat list?  What were your results?

For reference, that bug is https://bugzilla.redhat.com/show_bug.cgi?id=233642
